IMPROVEMENT IN CLEANING BUTTON-WASTE.

I dilgt Srlgunle trfcrtrh in in this: Enters grant are making part of the same.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HAYDN M. BAKER, of Harlem, in the city, county, and State of New York, have invented a new and useful Process for Cleaning Cotton-Waste and recovering oils from the same; and I do hereby declare that the following is a full and exact description thereof.

- The nature of my invention consists in removing oils from cotton-waste, by dissolving said oils with coaltarbenzole or coal-tar naphtha while the said cotton-waste is immersed in the same, making use, at the some time, of any mechanical appliance which will procure and communicate alternate motion, agitation, and compression to the benzole or naphtha.and cotton-waste during the term-of immersion. A

The next stage consistain removing thc-solution of oils from the cotton-waste and conveying them to a distillatory apparatus, observing to press the cotton-waste bynnysuitalfie inefihah'frffihappiiance, tvdiseuga-go and separate the solution oi oils.

The cotton-waste dried is ready for use again. I The next stage consists in separating the coal-tar benzole To enable others to make use of my invention, I will proceed to describe it mor e particularly. I place any amount of saturated cotton-waste in a vessel, (capable of being made tight,) with suflicient henzolc or naphtha to eiiect a complete solution of all the oils contained therein, and then run off said solution and submit same to distillation at a low temperature, or at such temperatures or naphtha from the oils by distillation.

into a distillatory apparatus, as will disengage and distil over the bcnzole and naphtha from the oils.

The benzole and naphtha, or mixtures of each, may be used repeatedly.

The cotton-waste may be pressed and dried, and thenwashcd with a weak solution of soap or alkalics, and again dried, when it will be found to be perfectly clean, and with an uninjured fibre.

The advantage of this invention is, that it provides an economical method of cleaning cotton-waste, and recovering the oils contained therein, without injury to the fibre of said cotton-waste.

Claim.

What I claim as my invention, and desire to secure by Letters Patent, isi The use of coal-tar henzole or coal-tar naphtha, or mixtures of same, and their equivalents, for removing oils from cotton-waste, (or other fibre used for similar purposes,) and also the separation and recovery of the oils and solvents by distillation.
